It is a Black Walnut stock with Burl Maple Tip and Cap. My first attempt at a thumbhole stock. Now if I can just get it to shoot like I want it to. . . . . !! Being the Holidays (Christmas) and family in, I don't think that I am going to get a chance to do much with it for a week or so, too many things on the plate . . I really appreciate the information that you all have provided and I am starting to stock pile the components. When time permits I will put them together and head to the range . . . results pending . . :)
